Be it known that l, JAMES; P. Hooi/ine, c citizen oli the United States, residing at new ind useful improvements in Reinforcedoncrete liling, of which the following is u specification.

lio

My invention relates in improvements in rciiiiorced concrete piling, the object of the invention being to provide e piling ossembled in .sect-ions, es the pile is suoli, and iiinsturing a. (perfect juncture between the sections, en e perfect lock of the sections when the pile is complete.

A further object is to provide improved ineens for guiding the pile sections together, und so shape the interior ot the pile sectlons,

that they will be securely looked, and forni in effect, o single integral pile when filled i with cement utter being sunk.

. A further object is to provide en iinproved piling oi this character `which. is

especially adopted fior use with'connection'v bars or sections, orniing ocontiuuous wel A further object is to provide on improved piling of this character, which con be readily )raced sind support e continuous wall' made up of piling sections, against possibilityof backward movement by the force of water.

With these and other objects in view, the

v invention consists in certain novel' features of construction, and combinations 'end erimproved piling Wall. Figli, is on end View of Fig. 5. Figs. 7, 8, 9, l0, 1l and 12, are views of other modieetions. l

My improved piling; comprises e lowest section l, und as many upper sections 2, es maybe desired, to form e pile of any length. All of the sections nre composedo concrete reinoroed by metal inserte 3. The lowest section l is l rov'idedv/ith a central pipe or tube l', Whit: letter estendethroughout the length of the section, sind is cncliored there-- inly meses of o cross our 5, fast to the pipe,

i per end ofthe pipe which is ordinary orm :of

screw threaded, projects into zi'circular recess 6 in the upper end of section 1,. This upper end of section 1 is also provlded with a circuler groove 7 :it the upper end of its 6o recess to receive a circular flange or tongue 8 on the lower end of un upperse'tion, and form e neat joint between the sections. AllA of the upper sections Q are cast hollow, and

cored out at their ends, forming a recess 9,

-oit approximately the saine sha ie as the recess 6 in the lower section l, so t et when the pile sections are filled with cement, they will lbe eiectually locked together by these adjacent recesses. The upper sections are all 73 provided with central collars 10, connected to the sections by means of arms 1l, em-a bedded in the concrete wall, and longitudined bars or strips l2 connect the collars l0, so as' to thereof. y

In driving the lowest section 1, a pipe 13 is screwed onto the upper end of pipe 4.-, und writer Aunder hydraulic pressure is forced through the 'seid pipes toispluce the sund 1180 :ind gravel-end allow tho-pile sections to sink. When this pile section has sunk purtially, on upper section is lowered onto section l by ineens of its` (rollers 10, the col lors l0 being ositioned on the pipe 13, serve 8o as guides to direct the section 2 into position over scid section 1, so es, to compel the tongue or flange portion 8 to ride into the groove portion 7 of the lower section and insure' e perfect juncture of the sections. 90

All of the' upper sections ore'guided into position onthe pipe 13 in this manner until the 'pile is of the desired length, when pipe 13 is turned to unscrew it from pipe section e, the latter bein r its anchor 5. lll/'lien pipe section 13 is entirely removed, the pile is lilled with cement, which when hardened, forms in elleet, a continuous solid integral pile.

The advantages of a pile of this character /100 are many. rlhe pile sections conA be made end transported from placeP to place with .comeretively smellexpense, :indcenelas: sem led in close quarters, such es., under the floor oi a building and the like, which needs pile stren herring, in which position, the pile could not possibly be used. l i

As shown in Figs. 3 end 4, the guide collclrs may be dis ensed with, Where the pile scribe cssemble above the Water level.

, In idigs.. 5 sindv 6, l have illustrated two of p'revepttsmy lateral movement 75 l held against turning by 95 these piles, made with longitudinal dovetailed grooves 14, to receive dove-tailed tenons l5, on the ends oit concrete bars 16, which latter are sunk by ineans ot jets of water, and connect the pilesv to forni a continuous wall. I

In Figs. 7 and 8, l have shown a .slight modification in whichr the piles are provided with parallel dove-tailed grooves 'lT to receive the dove-tailed tenons i7, ot narrow bars 18, and forni, in elitect, parallel walls, between which a filling ot' cement is to be provided, to provide a solid wall. Figs. 9 and 10, illustrate a modified forni of connecting bar 20, which is east hollow. and is adapted to he filled with cement.

ln liigs. 1l and l2, illustrate an iniproved. inanner of suppiirting a wall coniposed or pile, and hars as above explained, in which a post or pile 2l is sunk inte the ground and disposed at an angle, and this pile or post 2l and the piles i2 of the wall are provided with dove-tailed grooves 2? to receive braces or props 24, composed of concrete, and ettectnally support the wall, ,terne ing a'perfect brealiwater, orothcr piling ot' this kind.

Other changes might he made in the general form and arrangements ot parts clescribed without departing from my invention, and hence do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention..

Having thus described my invention what l claim as new and desire lo secure by Letters Patent is:

l. A pile comprising tubular sections, having tongue and groove connection hetween thein, said sections having enlarged recesses at tliei1 adjacent en ds, adapted to receive a filling of concrete therein.

9.. ln a Dile, the combination with a. lower section, o a pipe anchored in and extend ing through said lower section and having a screw threaded upper end, an upper section constructed to forni a tight vjoint with the lower section, a removable water supply pipe projected through the upper section and screwed onto the pipe in the lower secaimee tion, and collars carried by the upper section and movable on said removable pipe, to

forced concrete, a water supply pipe an` chored in and extending through the lowest section and project-ing upwardly into a recess in the upper end of the lower section, a tubular upper section constructed to tit upon the lower section, and having a recess in its lower end. a removable pipe constructed to pass through the upper section and connect,- ed with the pipe in the lower .section for the admission of water thereto, and 'said .sections adapted to receive a tilling of ccnient, locking thein together to form a continuous pile.

`rl. pile comprising tubular sect-ions, having tongue and groove connection between them` said sections having enlarged recesses at their adjacent ends adapted to receive a. filling ot concrete therein, and said sections having registering grooves in their opposite tacos, connecting bars, and tongues on said connecting bars adapted to enter the grooves in the piles to forni a wall.

5. A pile comprising tubular sections, having tongue and groove connection between thein, said scctions'having enlarged recesses at their adjacent ends adapted to receive a filling of concrete therein, and said sections having registering grooves in their opposite faces, connecting bars, and tongues on said connecting bars adapted to enter the grooves in the piles to t'orin a wall, said pile. sections having registering grooves midway betveen the iist mentioned grooves, an in'- clincd pile or post having a groove therein, and props having tenons at their ends adapted to enter the last mentioned groove in said pile sections and in the inclined post or pile, substantially as and :tor the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
